Eight green DDR4 LRDIMM sticks with gold contacts in a row

OWC

OWC 2TB (8x256GB) DDR4 3200 PC4-25600 CL22 8Rx4 288-pin 1.2V ECC Load Reduced LRDIMM memory upgrade

SKU CH-1BV5-8EXHR

Eight 256 GB DDR4 3200 CL22 ECC load-reduced DIMMs totalling 2 TB for HP ProLiant DL385, DX360 and DX385 Gen10 Plus servers

Capacity 2TB (8 x 256GB)

  • 2 TB total capacity with eight 256 GB modules
  • DDR4 3200 MHz CL22 for high-throughput server workloads
  • ECC load-reduced design protects data integrity in critical applications
  • 2 V operation reduces power draw per DIMM
  • Backward compatible with 2133, 2400, 2666 and 2933 MHz systems

Server-grade ECC LRDIMM kit

This kit provides 2TB of DDR4 memory across eight 256GB load-reduced DIMMs. It is built for HP ProLiant DL385 Gen10 Plus, DL385 Gen10 Plus v2, DX360 Gen10 Plus and DX385 Gen10 Plus servers. The modules operate at 3200MHz with CL22 latency and 1.2V power. They are not compatible with standard desktop computers.

ECC load-reduced architecture

The single specification that decides fit is the ECC load-reduced design. This memory cannot be mixed with unbuffered or ECC registered modules. It replaces HP part numbers P06039-B21, P06039-H21, P06039-K21, P43172-B21, P07654-H21 and P07654-B21. The 288-pin form factor matches the target server slots exactly.

2TB capacity for dense workloads

Eight 256GB modules deliver 2TB total capacity for virtualisation, large databases and in-memory analytics. The kit runs at 3200MHz and drops to 2133MHz, 2400MHz, 2666MHz or 2933MHz where the platform requires it. It will not work in systems that only accept unbuffered or standard registered DIMMs.

Questions about this item

What does the 3200MHz rating deliver once the modules are installed in a compatible HP ProLiant server?

The kit runs at DDR4 3200 with CL22 timings at 1.2V, providing the rated bandwidth when the server's memory controller operates at that speed.

How does the PC4-25600 designation limit real-world performance?

PC4-25600 identifies the DDR4 3200 standard; the modules will down-clock to 2933, 2666, 2400 or 2133MHz if the platform requires it.

What physical slots and clearance do these 288-pin LRDIMMs need?

Each module uses a standard 288-pin DDR4 DIMM slot; the kit contains eight 256GB load-reduced DIMMs for servers that support 8Rx4 ECC LRDIMM population rules.
